Yesterday, a young man, just graduated from dental school, came to the store to sell us a small batch of casting gold leftover from his casting classes. We tested his gold as 14K, then weighed and valued it for him. He left the store to get his identification so we could make the transaction, but […]

Jenny was able to train on 3Design in March, and she’s been able to produce some wonderful pieces with the new software. I had a medical issue and couldn’t take the training until now, so my skills will come […]

These gorgeous perfectly matched solid black opal earrings illustrate the global reach of the gem trade. We acquired the stones a few years back from an Aussie opal cutter in Lightning Ridge, Australia, then sent them to Nepal last year. Each leg of their journey was about 8,000 miles, so these opals have traveled the […]

Cat's Eye is an optical phenomenon seen in many different gems, including emerald, aquamarine, and tourmaline, to name a few, but the classic Cat's Eye effect is best exhibited in the […]

We made this grand gent’s ring about 20 years ago, of platinum set with a stunning oval Tanzanite weighing 5.36 cts. It was interesting to see just how the platinum mounting and the Tanzanite were holding up– Our client Bill is a race-car driver by avocation, so we’re sure the piece got plenty of banging […]

We just appraised this beautiful bright yellow ~2 ct. round diamond for a client. She had inherited the stone, which was accompanied by an appraisal from a gemologist which described it as a “Canary Yellow” diamond, which implied but didn’t state specifically that the stone was natural-color. Our client said the diamond had originally been […]

This basic design, where a colored gemstone is surrounded by a circlet of diamonds, has been a favorite for centuries. Since everybody and their uncle has been doing versions of the ring, we might […]
